    PR libstdc++/49204
    * include/std/future (__future_base::_State_base::wait()): Use lambda
    expression for predicate and remove redundant test.
    (__future_base::_State_base::wait_for()): Return future_status and
    use lambda expression for predicate.
    (__future_base::_State_base::wait_until()): Likewise.
    (__basic_future::wait_for(), __basic_future::wait_until()): Likewise.
    (__future_base::_Async_state): Replace with _Async_state_common
    class for non-dependent functionality and _Async_state_impl class
    template for dependent functionality.
    (__future_base::_Async_state_common::_M_join): Serialize attempts to
    join thread.
    (__future_base::_Async_state_common::_M_run_deferred): Join.
    (__future_base::_Async_state::_M_do_run): Replace with lambda.
    * src/c++11/future.cc (__future_base::_Async_state_common): Define
    destructor, so key function is in the library.
    * config/abi/pre/gnu.ver: Add exports for ~_Async_state_common.
    * testsuite/30_threads/packaged_task/members/get_future.cc: Expect
    future_status return instead of bool.
    * testsuite/30_threads/shared_future/members/wait_until.cc: Likewise.
    * testsuite/30_threads/shared_future/members/wait_for.cc: Likewise.
    * testsuite/30_threads/future/members/wait_until.cc: Likewise.
    * testsuite/30_threads/future/members/wait_for.cc: Likewise.
    * testsuite/30_threads/promise/members/set_value2.cc: Likewise.
    * testsuite/30_threads/promise/members/set_value3.cc: Likewise.
    * testsuite/30_threads/promise/members/swap.cc: Likewise.
